A knockout like the Lulus Rare Beauty Navy Blue Tulle Backless Maxi Dress doesn't come around often! Stunning sheer tulle (atop a matching knit liner) sweeps across a pleated, plunging bodice and a high, banded waist, both supported by adjustable skinny straps that crisscross over a sultry open back. Full maxi skirt gets boost of sexiness thanks to alluring dual side slits that peek out beneath a sheer layer of tulle. Hidden back zipper/clasp.
